Abstract: An easy opening container component and a method and tools for forming the same are provided in which the container component includes a substantially rigid inwardly displaceable opening panel including a V-shaped weakening indentation therearound in the public or exterior surface of the component providing a fracturable web at the root of the indentation adapted to be fractured by inwardly directed pressure digitally applied against an integral outwardly projecting deflectable portion of the container component around the opening panel. The V-shaped indentation may be formed in the exterior surface of the container component while the opposite surface lies against a rounded anvil which forms an inwardly concave undersurface on the nonpublic surface of the container component, and may be formed in sheet metal without destroying the integrity of a protective coating on the interior surface thereof.

Abstract: A construction for a digitally openable container closure which includes at least one inwardly displaceable opening panel each of which is defined by a fracturable web forming a locus of separation of the opening panel from the adjacent portion of the closure, an integral deflectable portion projecting outwardly from the closure adjacent the fracturable web around each opening panel and weakening lines in the closure adjacent each opening panel extending across the closure between the opening panel and a central panel of the closure to facilitate displacement of the deflectable portion of the wall in response to digitally applied inwardly directed pressure to initiate fracture of the web and permit inwardly displacement of a separated opening panel.
